The Incan-German war (in Germany sometimes called the Der Krieg sieben Jahre) lasted between 1806–1813 and involved all of the Incan and German empires. The war started with the German Empire, Spanish Empire, Portuguese Empire, Incan Empire and Great Britain. Portugal (on the side of Incans) and Spain (on the side of Germany) were drawn into the conflict later. It resulted in some 70,000 to 140,000 deaths and significant changes in the balance of power and territories of several of the participants. The war began with Frederick the Great of Prussia's invasion of Patagonia.
